A vessel has nitrogen gas and water vapours at a total pressure of 1 atm. The partial pressure of water vapours is 0.3 atm. The contents of this vessel are now transferred into a new vessel having one-third capacity as of the original vessel at the same temperature. The total pressure of the system in the new vessel will be

Text Solution

Verified by Experts

The correct Answer is:
`2.4` atm
`P_(N_(2))+P_(H_(2)O_((V))=1` atm, `becauseP_(H_(2)O)=0.3` atm ltbr. `thereforeP_(N_(2))=0.7` atm
Now new pressure of `N_(2)` in another vessel of volue `V//3` at same `T` is given by:
`P_(N_(2))=2.1` atm
Since aqueous tension remains constant, and thus total pressure in new vessel.
`=P_(N_(2))+P_(H_(2)O)=2.1+0.3=2.4` atm.
